At least Rubin's headline was tongue-in-cheek.
The Wall Street Journal headline was more of a tease, as evident from the first paragraph:

An international meeting on Syria's crisis agreed to support the creation of a transitional body in Syria that would lead a United Nations-backed political transition, but left open whether and how President Bashar al-Assad would have to step aside.

How nice of the world to give Assad the option.

And to help clarify, we have the ever-helpful, Kofi Annan:

Kofi Annan, the special envoy on Syria who convened the meeting, said Mr. Assad's role in a transition would have to be determined by Syrians themselves. He said he hoped to see results from the process "within a year."

So there you have it.
A meeting of countries has gotten together to stop Assad's murder of over a thousand Syrians by giving Syria a choice if it would like to keep Assad as a leader or not--if Assad will be good enough to go along.

Of course, there are more to the consequences than that--as Barry Rubin points out:

That's right! The powers have agreed to a transition to a new government which will go into effect as soon as the current dictatorship agrees to be overthrown and its rulers flee for their lives and watch their supporters probably be massacred. Perhaps the world will then install a new Islamist government in Syria, forcing it down the throats of the real democratic opposition, which will be dedicated to spreading revolution and striking against Western interests.
